LL? "GFiifiiON forming of Letters Ratei/it No, 719,330, dated January27, 1903. Application iiled November 20, 1900. Serial No. 37,131. (Nolnodeli) Be it known that i, THORVALD HANSEN, of Everett, in the countyof Middlesex and State of Massachusetts, have invented a new and usefulimprovement in 'lhread-Viinding?r Machines, of which the following; is aspecification.

in all thread-windiim machines of that class in which the thread-guidelies aca-inst the growing` cop as the periphery of the cop increases insize,and consequently travels faster and faster, it draws the threadfrom the source of supply with greater and greater rapidity, so thatmore and more friction is caused by the thread reeving through thevarious guides, and consequently there is an apparent increase in thetension, so that the outer layers of thread are usually wound tighterthan the inner layers. ils a result with some kinds of thread the endsof the cop are inclined to bulge and the cop as a whole is not assightly nor is it as smooth and well built np as it should be.

liy invention is intended to overcome these faults; and it relates,broadly speaking, to

certain mechanism described below, which is connected directly to theguide for relieving the cop from increasing pressure as it increases insize, this relieving:r of pressure being accomplished by decreasing thetension and at the same time by decreasing materially the pressure bymeans of which the guide is laid against the cop. lt will be obviousthat while both these means cooperate for this purpose either of thesemeans may be used without the other when thought best.

My invention therefore consists, first, in an improved means forcontrolling the pressure with which. the guide bears upon the cop;second, to means for relieving the tension upon the thread as the copincreases in size. l have shown my improvements applied to a machinesimilar to that described in Letters Patent No. :Siti-,530, granted tome November 30, 1897; but it will appear that they may he appliedequally well to other winding-machines. in the drawings l have not shownmeans for applying; power to the various shafts, as those means arefully shown and described in the said Letters Patent, and by comparisonof the drawings of said Letters Patent with the drawings forming a partof this specification the similarity of arrangement of the severalshafts in the two machines will be fully understood.

In the drawings forming part of this specification I have shown theinvention in the best form now known to me.

Figure l is an end elevation, and Fig. 2 a front elevation, of so muchof the machine as embodies my present invention, Fig. 3 being adiagrammatic detail showing the parts in their various positions, asdescribed below. Fig. t is a detail illustrative of the yieldingguide-support.

A is the base, which may be suitably supported upon a post or in anyother convenient way. Upon this are mounted two up rights B B'. Theupright B carries at its upper end a journal-box C and also asubstantially semicircular frame D. The upright B' also carries ajournal-box C', opposite the journal-box C in the frame D, and asubstantially semicircular frame D', corresponding!i to the frame D uponthe upright B. These frames D and D contain semicircular guideways inwhich slide the sliding carriage J2, as described below. The upright B',however, extends above the frame D' and carries two journal-boxes E 1',in which are mounted shafts F G, one of which, F, carries thewinding-spindle F'. The other shaft, G, as shown, carries a cutting;mechanism which forms no part of this invention, and hence is not hereindescribed. These two shafts F G are geared together by fears F2 G', theshaft F being,r a continuation of the shaft carrying' the clutch in mypatent above referred to,4

the gears being the same as those shown in my prior patent, and themechanism to the left of the gear F2 (shown in Fig. 2) being for thepurpose of applyingr power to the various spindles and being similar tothat shown in said patent.

H is the traverse-cani, also as shown in my said patent, which cam ismounted upon the shaft H', which passes through the journalboxes O C', cbeing` an adjusting-screw which closes in the end of the journal-box C,thus preventing end movement of the shaft I-I'. Power may be applied tothis shaft as in my previous patent.

J is the guide, which, as shown, is provided with four guide-eycsj, cachof which carries IOO a thread M, the machine as shown being adapted towind four separate cops upon the Isame tube, the four cops being markedj' ,7'2 ,7'37'4 and the cop-tubef.

The guide J is mounted in ways J' in a sliding carriage J2. mounted toslide in ways formed in the opposing sides of the semicircular frames DD', these ways being located slightly above the cam-roll H. The ways J'enable the guide to traverse parallel with the axis of the spindle F',andthe guide is caused to travel by means ot' a pin h, which runs in thecam-groove h of the cam H. The rotation of the cam, therefore, causesthe guide to traverse longitudinally of the spindle, and the ways denable the carriage J2z to travel away from the spindle, taking with itthe guide. In order that the guide may be held up to its work, I haveshown the following meansz` Upon the table A are mounted two uprightsupports K, in which is mounted a rock-shaft k,carrying a rocker-arm11;',which is connected by a connecting-rod with one side of the slidingcarriage J2. Upon the other end of the'rock-shaft 7c is mounted anangle-lever one arm of which, 7a2, is connected by a connecting-rod 7a4with the other side of the sliding carriage J2. From the other arm h5 ofthis angle-lever depends a hanger 706, carrying weights k7. The point ofconnection between the hanger 7c and the arm 755 is made adjustable, soas to adj ust the position of this hanger upon its arm, and so adjustthe leverage, which may be desirable in certain cases.

It will be seen from Fig. 3, where the position of the guide and themechanism connected with it when the winding begins is shown in dottedlines and the position of the guide against the cop when it is wound isshown in full lines,thatin the first instance,owing to the shape of theangle-arm, the weight k7 acts with extreme eiiciency to hold the guideagainst the cop. When, however, the cop has been filled, the position ofthe hanger with relation to the fulcrum ,7c of the lever has changed, sothatits eiectivenessis reduced toa minimum, this being desirable Jforthe reasons stated above.

I prefer to curve the upper end ofthe hanger, as is shown, in order thatunder certain circumstances its point of connection with the angle-levermay move above the rock-shaft, as shown in Fig. 4f, so that the weightwill be absolutely neutralized.

The tension mechanism will now be de.- scribed. It consists, generallyspeaking, of a brake which is applied to ashat't turned by the runningthread and so controlled by the position of the guide that when theguide lies against the spindle or cop-tube the brake is applied with itsmaximum force and when the guide is pushed away from the spindle as thecop grows the brake is relieved either whollyorentirely,according tocircumstances. I have shown the brake in the form of a weighted straphangin g over the brake-whe el mounted on a shaft turned by the runningthread, the position of the brake being controlled by suitableconnecting mechanism with the sliding carriage which carries the guide,this being a convenient and simple method of construction; but othermethods of construction embodying this same idea will suggest themselvesto those skilled in the art.

YI have shown it constructed for four threads;

but it may be used for a greater or less number, as will be understoodby any mechanic, thesame brake, however, serving for all thetension-disks. The special description of this mechanism is as follows:L is a bracket attached to the front of the table A and having hangingtherefrom a Xed arm L', carrying one of a pair of brushes L7, the otherbrush being attached to a hinged arm L2, the position of which iscontrolled by a spring L3, which causes it to hold the two brushes inContact. From the bottom of the arm L' projects laterally a second armcarrying a series of eyes l, one for each thread, through each of whichthe thread M passes up from the spool or other source of supply, andabove the brushes is a second series of eyes Z,through each of which athread again passes after passing between the brushes. Upon the bracketL are also mounted two idler-rolls L4 L5 for each thread, the onelocated to take the thread from the upper eye L and the other to deliverthe thread to its guide-eyej. Between each pair of idler-rolls runs alarge grooved tension-wheel N. These tension-Wheels N are mounted on ashaft n, on which is mounted also the brakewheel N', the shaft beingcarried in journals, one of which is formed in the bracket L and theother in an arm L6, projecting from the bracket. There is also mountedon the shaftn, free to turn thereon, a hub having on one side of itgear-teeth n and on the opposite side a fan-shaped arm n2, from whichprojects a pin n3, from which hangs a strap n4, carrying at its lowerend a weight m5. The gear-teeth n' mesh with the gear-teeth of asegment-arm n, which is pivoted to the bracket L, forming a lever thefarther end of which, n7, is connected by a connecting-rod 'ns with thesliding carriage J 2. These parts arearranged together, as shown inFigs. l and 3. (See especially Fig. 3, where the two positions of thesliding carriage J2, carrying the guide J, are indicated in dotted andfull lines, as eX- plained above.) It will be seen from examination ofthis view and also from an examination of Fig. l, in which the cop ispractically wound, that while the guide J is in close proximity to thespindle F the position of the pin n3, which carries the strap n4, issuch that the strap lies over the brake-wheel N; but as the guide isforced out by the enlargement of the cop the position of the arm n2,carrying the pin n3 and strap n4, is so changed that the brake-wheel N'is nearly or perhaps entirely free from engagement with the strap. It isdesirable that this arm n2 shall be provided with a series of holes inorder that the IOO IIO

position of the pin or may be changed to adjust the brake according tothe kind of thread to be wound, this adjustment being one easily madeIand easily understood by those skilled in the art of winding. Eachthread M, therefore, after passing through eyesZ Z and around a lowei1idler L4 passes around a tension-wheel N and then around a second idlerIf and from it to the guide J. The shaft n, which carries both thetension-wheels N and the brakewheel N', is caused to rotate by the draftof the thread or threads, the resistance to rotation-that is to say, thedrag or tension on the thread-being controlled by the strap which passesover the brake wheel, lthis strength diminishing, as will be understoodfrom the above description, as the guide .I moves away from the cop. Itwill thus be understood that as the cop grows both the tension on thethread decreases and the pressure of the upper end of the thread-guide.I upon the cop decreases, so that if, for example, the thread is softas the cop is built up it is not squeezed by the outer layers; but theselayers are all laid with only sufficient tension to keep them in placeand wind a hard cop, but without enough tension to cause the ends ofthecops to bulge.

As shown in the drawings, one brake-wheel and strap is shown to controlthe tension of four threads, each of which passes through its own eyes,around its own idlers and its own tension-disk, the tension-disks allbeing mounted on the one shaft, and it is obvious that the number oftension-disks, eyes, dac., may be increased or diminished according tothe number of threads to be wound or according to the number ofguide-eyes of the guide J, and other brakes may be added, if necessary.

The cop-tube may be held in place on its spindle in any desired way--as,for example, bya collar f, which slides over the end of the spindle andis provided with a bayonet-joint of ordinary construction to hold it inplace. A similar winding operation may take place upon the shaft G, inwhich case the machine should be provided with a second set of tensiondevices, through which the thread should be fed to the cop-tube uponthat spindle or shaft. As shown in the drawings, however, that shaft isprovided with a mechanism for cutting the tube after it has been wound,which mechanism, however, I will not describe here, as it will form apart of another application.

It is believed that the general operation of these improvements will beunderstood from what has been said above. The tube being placed upon thespindle F and the threads being properly arranged each about its owntension-wheel and through its own guide-eye in the manner describedabove, the machine is started, and as the cop builds up the guide isheld against it with less and less power and the tension is graduallydecreased, the weights being adjusted according to the requirements ofthe thread to be wound. The cop with its four threads, more or less,being finished may then be cut into four cops by any desired means. Ihave found that itis simpler to wind small cops in this waynamely,winding them first upon a long tube and then cutting the tubefor thereason that the shorttubes are much more difficult to handle withoutinjury than one long tube.

yI have not specified the weights to be used either upon the brake orupon the hanger, as this can easily be done by experience. The weightupon the brake should be about half an ounce and that upon the hangerwhich controls the position of the guide perhaps two or three ounces,according to the thread. The shape of the cam-grooves 7L may of coursebe varied according to the traverse to be given to the guide.
